To all whom; it may concern: Be it knownthntI,HENRY-JANSEN HAIGHT,

- a citizen of the United States, residingin the .tem and Recording -panying drawings,

.ters Patent in Great Britain city of New York, in the county of New York and State of New York, have invented 'a new and Improved Electro-Magnetic Clock Sys- ThermoscopeComhined 'lherewithyand I do hereby declare that the following, is a full and exact description of the sam'efre'ference being had to the accomiuaking part of the specification. s

'Ihis invent-ion is the subjectmatterofi Letgranted to me, dated March 10, 1887, No. 4,135.

. My invention consists, first, in .a new and improved means of transmitting by electro magnetic power to one or more distant stop tions or localities the time-indications of a standard or other clock and of showing the same time on the clook-faces at the stations or localities-without requiring clock-work at thesaid stations, or localities, and thereby avoiding the necessity of any winding of clocks or ,other attention thereto; second, in the 'conibination,'with the said clock-time transmitter, of a comparer or verifier located in the vicinity of the transmitting-clock, whereby the correctness of the transmission of the time to the distant stations or localitics' is verifiedt third, in the combination, with the aforesaid time transmitting and exhibiting devices, of an electro-magnetic re ceiving and; recording thernloscope for the saiddistant stations or localities.

In the accompanying drawings, Figure 1 represents a top viciv of so mnch'ol afstandard or other'clock' as is necessary for the present-purpose andiof the electro-magnetic tiinc-transmitting mechanism combined with .the clock; Fig. 2, a rear view of the same; Fig. the rear view of the time-verifier em-' ployed inconnection with the clock and transmitter; ,Fig. 4, a rear view of the timetx ansmitting mechanism, showing the additional circuit-closing mechanism for connecting it with the verifier; Fig. 5, a diagram exhibiting the electriccircuit connections between the clock-transmitter, the distant stations or localities, and the verifier; Fig. the top View of the thcrmoscopic recording mech anism employed in connection with thetimethe clock time armature C is mounted transmitter; Fig. 7, a rear view of the same;

Fig. 7, a fractional face View of the tabletroll, with the worker and other parts connected therewith.

Like letters designate corresponding parts in allot the figures.

Referring to Figs. 1 and 2, I first describe transmitter without other parts.

Let A represent a clock-movementjor so much thereof as is necessary to show its connection with the electromagnetic time-trans: mitter, a indicating the face, I) c the minute and hour hands, respectivelyfaud d the com Upon the rear tral or minute-hand shaft. side of thehack platee of the clock is mounted the elcctro-magnetic time-transmitting mechanism, the essential parts of which will now be specified. First, an elctro-magnet B, of

the ordinary or any other'suitable construction, is properlyattac'hed to the clock. Its on a lever D,- which is pivoted on a pivot f, -projecting from the said clock-plate. The counterbalancing end of this lever is 'preferablyweighted, as at 9, so that the position of its pivot f may be as far from the electro-1nagnet as practicable. I also prefer to employalight counter-spring h, adjustable in tension, although it is evident that either an adjustable counter weight or spring may be made toserve-the whole purpose. This armaturelever actuated by the, electro-inagnet and counter weight or spring serves to close and open the electric circuit (represented in the figures) by the broken wires jj, which transmits the time-indications of the clock to distant'clocks or. clock-hands. The lever also serves to turn a circnit-closingrepeater, workaud frame are insulated from the electro-maguct, its armature-lever, &c., by interposing insulating material at their res pective attachments to the back plate 6, as indicated by heavy black lines in Fig. 1. The

central minute-hand shaft or spindle d of the clock is of sufficient. length to extend to the rear side of the electromagnetic mechanism, but'does not come in metallic con nection with the same, except at the proper-times for closing the circuit of a local battery E, the circuit-wires is k of which connect at one end with the clock-frame and at the other end io-witlijit. On the face of the repeater is a pro- Strikes the same to close th e local circuit.

with the electromagnetic mechanism, incl udiug the wires of'thc electro-magnet, also in the circ uit,'es indicated in the figures by wires and dotgeddine connections, A part of this circulfijisa circuit-closing repeat-er F, which ordijuarlly consists of a. disk or wheel mounted to ,turn freely on a tubular pivot Z, attached to the.

piste e and surrounding theclock-sha-ft d, but notbein'g in metallic contact or connection jectiug contact-pin m,and projecting radially from'the clock-shaft (Z is an arm at, just back of thecircuit-closing repeater, but not in C0111 .on' iis's circular edge of sufiicientfineness or ratchet-teeth. The circuit-closing distance apart to correspond with any prescribed portion of an hour, provided for b a complete revolution of the fore thenee of {the clock. Thus if the repeaterdiskis constructed to make just one revolution ,each hour, and there are sixty ratehet-teeth'on the same, it will be moved every minute. If there are one hundred and twenty ratchet-notch es, the circuitrclosing rcposter will be moved every half-minute, and so in proportion with any desired number of repeater is turned one notch at a time by a pawl 2), pivoted upon the armature-lever I), a light spring q serving to hold it to the tecthof the circuit-closing repeater. A detcnt -r, pivoted on a bracket 8, takes intothc ratchet-teeth of "tholjepeater disk to prevent any backward motionof the circuit-closing repeater. The

detent-is held .to the ratchet-teeth by a suit-' able spring t.

Thus organized, whenever the m iuutc-hand of the clock' advances a prearranged. part of an hour, as a minute or half-minute, for instance, its shaft (Z, carrying the circuit-closing hrm 11, moves the said arm forward in to contact with the pin in on the repeater-(lisk,t-hercby closing the local circuit and causing, the electro-magnet B to he magnetized, whereby the armature-lever l) is brought down and the pawl}? thereon is made to move the repeater-disk one notch lrn-wzn'd, thus moving the contact-pin m forward again away .the contact-arm 11- and breaking the local circuit, so that tho immature-lever is again raised by its countcrspring. Again, as the minute-hand 'moves forward another divis- '.ion the circuit-closing arm n comesouce more into contact with the pin m and closes the local circuit, whereby the pawl 1; moves forward the repeater-disk another notch and breaks the circuit again. Thus the repeaterdisk is co'n'tinually moved forward one notch.

at a time as fast as the minutelniud of the clock moves round an equal pa rt of :1 circle and closes the circuit, so that the repeateri or regulated by as it descends,-

minute-hand, be-

- 4 Q circuit, thus accomphslung from disk makesarcvolution each hour; orit might.

instrumentis so arranged that a certain number of notches on the diskwill correspond with a complete revolution of the minute hand shaft, indicating an houro'f time. It is only necessary, theri, thattthe main circuit extending to the distant clocks to be moved the transmitting-clock shall be closed and broken simultaneously with the "local circuit, as above set forth, in order to make all of tl 1 c distwutclocks in ,the main circuitlo synchronize with the said transmitting-clock. For this tore-lever D is made to close the main circuit and acounter-spriug. or its equivalent breaks the circuit; as the Seal armature-'levcragain rises.

In the drawings I show-a 'inaiu cireuit -closcr, constructed and-arranged as follows:

A pivoted lever-moi hell-crank or other form, is connectcd'with one ivir'ej of the llihiu'circuit and an adjustable cdutact-piu-v isconilected with theotheliivjirej of t-he-inain cireuit, as clearlyshowltiu Fig. 'riuadjusltable presser-fiuger-w isattaclicd'to the 'ermatitre-lever, consisting, as rcpreseut'ed'yo'f a screw passed 'doyif'u' throughthe 'lever' and provided with an insulatedtip m, to presson the top of the circuit-closing leveru. Suitpurpbsc the armaable platinum or equivale'ut tips-are attached,

respectively, to the leveru and piu'v'toprd duce good electrical connect-ion. Th us when the local circuit-is closed, 'as above specified, and the armature-lever is finger w depresses thlev er'u and causes itto make contact \vithl-hc pin '11, and thereby close the main circuit Ajeouuter-spring g again raises the lever 19 as ture-levcr is raised, an'd so'breaks the main the pu rpose above specified. The leveru and stud in' which the pin 1 is mounted are properly secured to the d rzlwn "'its' pressersoon as the arms clock-plume,butareinsulated therefrom. An

adjustable stops is located above the armatitre-lever D to limit its upward movement; and regulate the distance through which it vibrates as the local battery.cire uib isjclose'd and opened.

Any construction of time secondary clock or clock-hand movement with a. clock face in which the minute-hand shaft; or spindle may bc--t urncd. by a ratchct whecl thereon the maiucircuit of and a pawl actuated byan eleetro-hmguetliu theclock-t-ransmitter may be employed.

letters of reference ou'thedrawing the electro-magnct B, armaturcdever D, clock-face a, minute and hour hand shafts h c, minute-hand shaft d, and back plate a. Two battery-circuits are also connected with this verifier, but differently arranged from those of-the'transmitter. Thus the wires a.

t a, which connect with the wires of the electro-magnet B, are connected with the main circuit, while the wires 10 k are in the local circuit of the transmitter and are marked by the same letters. Thearmature-lever D inthis instrument is insulated-and forms part of the local circuit. The end of the lever also presses upward against the key-le'-'er G, which also is insulated, and in the local circuit and turns on'apivot b. Tli'ej 'nd ofthe key-lever in turn p'resses upwar against an adjustable contact-pin e in a binding-post d, to which one end' of the local circuit-wire k is attach ed.

The key-lever has a suitable spring e, by

which it is kept pressed down upon the armature-lever D, while the retracting" pring 7aof I the ar nature-levcris of sufficient trcngth to I the electro-maguet B.

raise the leverand'also press uplth key-lever to the contact-pin 0 against the f rce'of the spring e of the said key-lever; b/ht when the armature-lever is depressed hy 't'l ljaction of the elect-ro-magnet B, when 11s circuit is closed, the spring 6 holds the key-lever G down upon the armature, thereby separating -it from the contact-pin c and/breaking the localcircuit. As soon as the ctr cult connected with the main circuit and passing through the electro-magnet B is again broken the armature-lever is again raised and closes the local circuit. A pawl 19 on this/armaturelever talres into. ratchet-notche 0 don the periphery of a disk oi wheel ll. This ratchetwheel has a connection with the armature lever D, similar to thatof the repeatcz dis'lc in the transmitter; but'its function is different,

tional circuit'closer and breaker operated by the armature-lever for a second local circuit. All the other parts of the .transinittingdnstrument remain the same, as indicated by like letters of reference; but the insulated tip :t of the presscr-finger w may be enlarged, so'as todepress the additional circuit-closer upon its adjustable contact-pin g, insteadof using a separate presser-finger,which, however, might be employed. The wire h for this local circuit is connected at one end with the contact-pin g. Thus it will be seen that when the armaturedevcr D is depressed by the closing of the local battery-circuit, as before set forth, the said lex'er will depress both circuit-closers u. and f, and thereby simuL taneously close the main circuit and the additional local circuit provided for by this con struction of the transmitting instrument.

The operation and function of the verifier,

in connection 'with the transmitting-instrument and the main circuit leading to distant;

stations or localities, where secondary instrumeuts are placed in the said main circult, Will be understood by reference to .lfig. 5, which is a diagram showing the connections of the said instruments bya suitable arrange.

The-dia- 8o ment of the mainland localcircuits. gram also illustrates the manner of multiplying the number of relay and secondary instru ments an indefinite extent. I show at the upper right-hand part of the 'figure the outline of the principal parts of the transmining-instrument; under the same, corresponding parts of the veritying-instrument; to'theleftof'the-transmiding-instrument,the, principal parts of the two secondary instruments in diflicrent'places inthe main circuit of the transmitting-instrument, and still farther to the left outlines of two other'secondary instruments, with dotted-line circuitwireconnectious with the otherinstrnments.

(Shown to indicate the manner of the indeii- '95 hits extension of the number of the second ary instruments.) Like letters indicate parts of these instruments corresponding with like parts of the instruments described in the formerfigures of the drawings. Ishow thelocal 16o hatter-y E and how the regular local-circuit ,wires I; k connect the transmitter and the verifier; I also show here how thewires h h of the second localcircuit connect the transmitter and the verifier. wires j j are represented in the complete circuit through the transmitter, two secondary clocks, the main battery-Land the ground connections. Also by dotted lines there is shown an extension ol'the main-circuit wires to two 1 1o othersecondary instruments. An additional circuit (represented by the wires 0. a) conheels the transmitter, the secondary instruments, and the verifier for the purpose incident with the main circuit, as shown,and the main battery I may serve for both those circuits; also, partsofithc second local circuit it may coincide with parts ol the rogulnr local circuit lo, as shown, and one local I20 battery sufiices for both.

I will now trace the successive movements of the instruments and the courses of the circuits to illustrate the operation of the instrumcnts. the transmitter at any time reaches the coin tact-pin m on the repcatcrdisk F, the regular local circuit is closed, and elcctro-lnagnet ii is magnetized mature-lever D is depressed. of the armature-lever presses down the second local-circuit closer f, Fig. 4, and closes the second local circuit ,h, which, also passing thereby the and the arthrough the electro-maguct 13, keeps the arma- The main-circuit I05 I l I of the vorihcation.

In Figs. 6 and 7 I show a means for. movtablet orpaper roll-of a a time-movement electrically transmitted, as by the transmitting-instrutherewit-h an electromagnetic thermosoopic receiver.

and described in lines forty-four to one hon dred-and twenty five, inclusive, of the second page of the specification of the same; and since I make no claim to the construction or any-combination of the same in the present case a full view-or detailed description thcrof is herein unnecessary.

Now a main object of the present invention is to ap'ply such a systern to the clock-timetransmittihgf system set forth in the present specification, so that continuous temperature-records of the trans mining-station maybe accordedat each of the receiving-stsmions'. Accordingly at each of the receivingstationsa receiving and indicating thermoscope is. arranged inbonnedtion with a secondary clock in ,thenlanner shown in Figs. 6 and 7.
